0257 - Experiment / Experiência

Steve is conducting an experiment at Perdigões. Using pit
50, that we excavated last year, to cow bones were buried, one with cinnabar
spread on it, the other painted with a mixture of cinnabar and egg yolk. They
will stay there for a couple of years and then excavated, recovered and
analysed. The goal is to control diagenetic interference in the absorption of
mercury in the bones and get a better idea of what happened to human bones that
have high percentages of mercury.
